  • vRealize Operations for Horizon/Published Apps data is not displayed in new installation..
  • No topology data is sent to the adapter.
  • In the broker agent log file, you see entries similar to:

    ****** ERROR   Error happened in collecting topology. Value cannot be null.

    ****** WARNING TaskTopologyRefresh : no Topology returned by RefreshFullTopology


This issue occurs because the broker agent throws an exception if the connection to App Volumes environment is broken. This exception impacts the collection of the full topology.


To resolve this, use one of these options:
  • Fix the App Volumes connection issue.

    Note: This issue does not occur if the connection between the broker agent and App Volumes is corrected.

  • Deselect Enable App Volumes Monitoring when configuring App Volumes in the broker agent configuration. 
  • Contact VMware Support for the Hotfix releases.

    Note: Restart the broker agent after applying the resolution.
